Perdoo, a Berlin-based OKR-focused software startup, has decided to make its basic service free, potentially shaking up its growing, and somewhat crowded, market. “Objectives and Key Results,” a planning and management technique usually shortened to “OKRs,” is a hot space for software startups, with several raising in recent months.

WorkBoard and Gtmhub, for example, each raised capital for their OKR products in the last two months. WorkBoard raised $30 million, while Gtmhub added $9 million to its coffers. So many companies are operating in the space that TechCrunch created a compendium of sorts listing the players, simply to get our mind around who is active in the space as a partial, or pure participant.
